Why is my Kia Rio engine making a clicking noise?

I've noticed that my Kia Rio's engine has been making a clicking noise, even when the car is idle. What could be causing this issue and how can I fix it?

It is possible that there is an issue with your engine's oil levels. Check your oil level and make sure it is at the recommended level.

Another potential cause could be a problem with your engine's spark plugs. If they are worn out or dirty, they may need to be replaced.

You may also want to check your car's battery as a low or failing battery can also cause clicking noises in the engine.

If none of these solutions seem to fix the issue, it may be best to take your Kia Rio to a mechanic for a professional inspection.
